    JbTecWiz Support Centre -- generated fix script

    Fault : "There was a problem resetting your PC" -- Reset this PC fails
    Fix   : Use an in-place upgrade instead of a reset
    Source: https://jbtecwiz.com/support/win-rec-reset-failed

    Run as     : A mounted ISO of the same or a newer build
    Expect     : 90 minutes
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    The reset will not run and the machine needs repairing without losing
    anything.

    HOW TO UNDO IT
    Settings -> System -> Recovery -> Go back offers a return to the
    previous build for ten days.

    This script walks the fix one step at a time and asks before each
    one. Steps with no command are things you do yourself -- it prints
    those and waits. Run with -DryRun to print without executing.

Invoke-Step -Number 1 -Do 'Back up first, regardless of what the process promises.' -Manual

Invoke-Step -Number 2 -Do 'Download the current Windows ISO from Microsoft and mount it. The build must be the same or newer than the one installed -- you cannot repair with an older one.' -Manual

Invoke-Step -Number 3 -Do 'Run setup.exe from within the running Windows, not from a boot menu, and choose to keep personal files and apps.' -Why 'An in-place upgrade rewrites every system file while preserving applications, settings and data. It repairs almost everything a reset would have fixed, and unlike a reset it does not remove installed software.' -Command {
